Windows XP update: Go Slow

Before you consider updating your computer’s Windows XP to the latest version of Windows make sure your existing applications won’t crash when using it.
Cnn writesMajor computer makers recommend consumers install the update, but in many cases they also have a list of revised drivers and other software patches that should be installed before downloading and installing the operating system update.
A Microsoft representative said that that although the company has been pushing Automatic Update as the easiest way to download SP2, the company has been recommending customers check with their PC maker and other hardware makers to get any necessary driver updates. Microsoft also has its own list of software that may have compatibility issues or may work differently with SP2 as well as a page with links to PC makers’ sites.
